My 2012 macbook pro screen seems to retain some white images like the menu bar icons after i turn off the screen. What can I do to avoid making it worse and can it be fixed somehow? To reduce the risk of image retention on your 2012 Macbook Pro screen, you can try reducing the brightness level of the screen when not in use.

This may help prevent the retention of white images, like the menu bar icons, from becoming more pronounced over time.

If the issue persists, it may be worth considering having the screen professionally cleaned or replaced. It sounds like your MacBook Pro's screen may be experiencing a form of image persistence or burn-in, which can occur when an image is displayed on the screen for an extended period. Here are a few steps you can take to help prevent the issue from getting worse:

1. Avoid leaving static images on the screen for extended periods: Try to avoid leaving the same image on the screen for an extended period, especially if it's a bright or high-contrast image. If possible, set your computer to automatically turn off the display after a certain period of inactivity.

2. Use a screensaver: A screensaver can help prevent image persistence by displaying a changing pattern or image when your computer is idle. You can find and set a screensaver in the System Preferences > Desktop & Screen Saver menu.

3. Adjust display settings: Consider adjusting your display settings to reduce the brightness and contrast of the screen. You can do this by going to the System Preferences > Displays menu.

As for fixing the issue, you can try a few things:

1. Power cycle your MacBook: Turn off your MacBook and unplug it from the power source. Press and hold the power button for 10 seconds, then release it and plug the MacBook back in. Turn it on and check if the issue persists.

2. Use a screen saver or a dark mode: As mentioned earlier, using a screen saver or dark mode can help reduce image persistence.

3. Contact Apple Support: If the issue persists, you may want to contact Apple Support for further assistance. They can diagnose the issue and recommend a repair or replacement if necessary.
I'm confused now... I thought we were talking about **your** macbook pro screen?  I'm wondering why you changed perspective and started offering me advice as if I was asking about a screen problem.  

Were you perhaps giving those suggestions as an example of a better quality answer?
Thank you for the additional advice. If I may ask, how long does it usually take for image retention or burn-in to occur on a MacBook Pro screen?
